I have identified the source of the breakage on my box, but I don't really
think it's the same problem that Edwin is observing.
Namely, it turns out that some code in arch/x86/kernel/acpi/boot.c, as in
today's linux-next, doesn't really make sense, because we have two conflicting
DMA-based quirks in there for the same set of boxes (HP nx6325 and nx6125) and
one of them actually breaks my box.
I have reported that already, but it probably got lost somewhere.
Below is a patch that fixes things for me, on top of today's linux-next.
Please apply.
Thanks,
Rafael
